Abstract:
In the present study, the synthesis, characterization, thermal and optical properties of poly(methyl methacrylate)(PMMA)/organomodified montmorillonit clay (OMTAB) nanocomposites were investigated. PMMA/nanoclay composites were synthesized by in situ polymerization method. Organomodified montmorillonit clay and PMMA/OMTAB nanocomposites were characterized by FTIR technique. The interlayer spacing of the organoclay platelets and the polymer clay nanocomposites were determined by X-ray diffraction spectroscopy. It was determined that the clay dispersion in the polymer matrix was exfoliated behavior. Thermal behaviors and thermal degradation activation energies of nanocomposites were determined by thermogravimetric analysis method (TGA). Polymer/nanocomposite thin films on the quartz surface were prepared by spin coating technique. The optical properties were obtained by measuring transmittance values in a UV-VIS spectrophotometer.
